P2229 RAM Code - Barometric Pressure Sensor 'A' Circuit High
Quick Answer
The Powertrain Control Module (PCM) continuously monitors this sensor for concerns. Common causes include Faulty Barometric Pressure (BARO) sensor, Barometric Pressure (BARO) sensor harness is open or shorted, Barometric Pressure (BARO) sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about P2229 RAM Code
1. What does the OBDII code P2229 mean on a RAM vehicle?
P2229 indicates that the Barometric Pressure Sensor 'A' circuit is reporting a voltage reading that is higher than the expected range.
2. What are the common symptoms of code P2229 in a RAM?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting, and the Check Engine Light being illuminated.
3. What causes the P2229 code to trigger in a RAM vehicle?
Common causes include a faulty barometric pressure sensor, wiring issues like shorts or open circuits, or a malfunctioning Engine Control Module (ECM).
4. Can a dirty air filter cause the P2229 code on a RAM?
A dirty air filter is unlikely to directly cause P2229, but it can contribute to air intake issues that might compound sensor problems.
5. How is the P2229 code diagnosed on a RAM?
A technician will use a scan tool to read live sensor data, inspect the barometric pressure sensor and wiring, and compare readings with the expected range for the current altitude.
6. Is it safe to drive a RAM with a P2229 code?
While it may be possible to drive, the vehicle could experience reduced performance and fuel efficiency. Prolonged driving with this issue may cause further damage.
7. How do you fix the P2229 code on a RAM?
Common fixes include replacing the barometric pressure sensor, repairing or replacing damaged wiring, and in rare cases, reprogramming or replacing the ECM.
8. Where is the barometric pressure sensor located on a RAM?
The barometric pressure sensor is typically integrated into the ECM or located near the intake manifold, depending on the specific model and engine.
9. Can a bad MAP sensor cause the P2229 code in a RAM?
Yes, if the MAP sensor and barometric pressure sensor share circuits or data, a faulty MAP sensor could contribute to the P2229 code.
10. Will clearing the code fix the P2229 issue on a RAM?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be addressed to prevent the code from returning.
